The following is a tabulation of water rates in use in Salina since 1925: Salina Water Rates in Cents per 100 Cubic Feet 1925~32 1932-36 1936-39 1939-44 1944 to Present Temp, Hat.( 1949-5:) ExceE:s ( R~fund.'? 16.8rJ; 13.5p 10.6~ 5.6~ Quantity Rate Rate Rate Rat.e Rate First 3,000 Cu.Ft. 22-1/2~ 20~ 17-1/2~ 15~ 11-1/4i Next 6,000 Cu.Ft. 18~ 15~ 15~ 12~ 9rj; Next 6,000 Cu.Ft. 12rf; 10rj; lOt q~ 6-3/4rj; Over 15,000 Cu.Ft. lO~ & 5~ 5~ 5~ 5~ 3-3/4rJ; b. A second reason for the necessity of increasing the water rates is the steady rise in the cost of material, labor and equiT'ment. The water works dollar, like the grocery store dollar, does not buy nl~o.rlY as much cast iron pipe, pumps, and chlorine as it did a few years ago. For this reason, prac- tically all the cities in the United Statesh:lV8 found it necessary to increase their water rates since the recent war, unless they already had excessively high rates before the recent increase in costs. c. A third necessity for higher rates is the large amount of improve- ments that must be made to the water distribution system. During the years prior to the recent war, there was a relatively small amount of large mains installed, and during the war practically no material was available for new construction. However, during the 27 years between 1925 and 1952 the popu- lation of Salina increased over 50%, and the usage of water increased 400%. The storage and pumping facilities were improved during those years, and small mains were provided for new areas, but th~ greatly increased rates of pumpage had to be forced through undersized mains. Also, the high mineral content of the Salina water has been constantly coating the interior of the mains and this further reduced their carrying capacities. As a result, in several areas of the City, it has become impossible to deliver water with -2- the pressure required to p~:'ovide satisfactory domestic service '3.nd tJ in:.Jure adequate fire protection. An engineering report was prepared in 1950, describing the deficiencies in the distribution system, and outlining a construction program to provide the necessary improvements. The principal work involved is additional elevated storage, larger supply mains and extensions to the distribution system as itemized later in this report. The amount of revenue required to offset the increased costs mentioned ab(',v~ will be discussed in detail later in this report. 3. Trend in Population and Water Usage. When establishing water rates, it is necessary to anticipate the probable future demand for water. If the amount of water used is constantly increasing, then the rates can be rather close to the actual production costs, as the overall unit cost is reduced slightly with increased output. Thi.s results from the fact that the over- head and fixed costs remain rather constant at all rates of pumpage,3nd only the pumping and chlorination costs vary almost directly vdth output. The population of Salina has been increasing at a relatively uniform rate for the past 50 years, but there is every indication that an accelerated rate of increase will occur in the near future. The Curve (Plate I) on the fOllo,ring page shows that the population has increased at a rate of about 4,000 persons every 10 years since 1900, which would make the estimated population about 30,800 in 1962. H~lever, because of the reactivation of Smoky Hill Air Force Base, a greater influx of population is expected through 1953, and we believe the population of the City in 1962 may be conservatively estimated at 32,000. The rate of water usage has been increasing even faster than the popu- lation, because the average amount of water pumped per capita per day has increased from 63 g~lons in 1926 to about 160 gallons in 1949.

The total amount of water pumped per year increased from 411 million gallons in 1926 to 1,560 million gallons in 1949. This information is sho~vn graphically on Plate II. It is assumed that a similar rate of increase in water usage ,viII continue in the future, and this should provide assurance that a proper rate schecule established now should be adequate for the future, and it might be possible to reduce the rate slightly within 10 years. The curve indicates that the total annual pumpage ~vill increase to an estimated 2,400 million gallons and that the average cons11mption per capita will increase to an estimated 195 gallons per day by 1962. a. Faulty Meter Registration. When a water meter is new it is a very accurate instrument, but as it becomes older it begins to run slow. This is especially true in Salina where the water is minoralized and contains iron and manganese, as these minerals form a coating on the interior of the meter which retards its movement and results in a low reel.ding. The Water Department has begun a program of reconditioning all water meters and restoring them to near their original accuracy, which should reduce the amount of unaccounted for water. b. Free Water. Large quantities of water are given to other City Departments each year, free of charge. During 1951 the amoVlnt of free water has been estimated at 4% of all water pumped, and was distributed about as follows: Flu3hing Sewers and Flush Tanks . . Washing Streets and Fighting Fires Hydrant Flushing . . . . Water used in City Parks .. . . . 7,476,000 gallons . 1,700,000 gallons . 5,100,000 gallons .36,800,000 ~allons Total Free Water Per Year 51,076,000 gallons -4- -l -Lf+ I I J~! ,I, , Iii' 'i J n-t 1=1: -l--i-w--1-J I 1 1 i ,+1_, : I f-~ : I I I -.

However, in that case, the General Fund of the City should be refunded by the Water Department. for office rent, administrative and attorney costs, and possibly some city taxes, and this would partially offset the charge for water. Also, it must be realized that the domestic customers, who use ovsr 70% of the water in Salina, are the same general group who get the most benefits from the parks and sew~rs. Therefore, no real injustice is done, and bookkeeping is simplified, if the cost of the free water given to the City is added to the customers' water bills. If a few thousand dollars additional revenue per year is needed in the Water Department at some future date, a charge could then be made against the other City departments for free water. . -5- SECTION 2 BASIS FOR THE WATER Ro\TE SCHEDULE 1. General. There are two principal factors to be determined when establish- ing a rate base: First, the total amount of revenue required must be com- puted, and second, a method of distributing these costs equitably over all users must be devised. The amount of revenue a water works should receive is the sum of the costs of maintenance and operation, plus the esti~ated cost of improvements and extensions, plus any depreciation allowance which may be included. Having determined the gross total of income needed, the next problem is to allocate this amount to the water customers on a basis that is fair to both large and small users. 2. A.W.W.A. Recommendations on Rates. For many years the leading engineers of this country have given a great deal of study to water rates and have expressed numerous theories on the subject. The American Water Works Association has attempted to analyze and evaluate the various theories advanced and to develop a workable pattern or formula by which all water works personnel could be guided in the preparation of water rate schedules. The first really constructive work on this subject was done by A.W.W.A. in 1923, and the recommendations made by them at that time have since then been used extensively, but there were many pertinent questions in rate making whi.ch were not settled at that time. Twenty-five years later, in 1948, the Michigan Section of A.W.W.A. again undertook the study of water rates in an attempt to clear up the questions not settled in 1923, and to analyze the results of the previous recommendations. Since theBe two studies and reports are by far the most thorough and logicil of any theories advanced, we have used the A.W.W.A. recommendations, with minor adjustments, as the basis on which to determine the Salina water rates. -6- 3. Applying the A.W.W.A. Formula t~ Salina Conditions. The computations~~ are rather long and involved and are not included in this report, but the figures are on file for inspection by anyone interested. The A.W.W.A. formula, when applied to the conditions in Salina, shows that the present water rates are well balanced, with the average intermediate rate about twice the wholesale rate, and the domestic rate about three times the wholesale rate. Therefore, in order to revise the present rates to provide the increased revenue required it will not be necessary to unbalance the present scale, but merely increase all rates, including the minimum charge per month, by a definite percentage based on the additional income required. The amount of increase necessary is determined in the follovdng section of this report. ~~ Required in developing the A.W.W.A. formula. -7- SECTION :3 AMOUNT OF REVENUE REQUIRED 1. General. The rate structure for a municipally owned water works should provide sufficient revenue to pay all operation and maintenance expense, pay all debt requirements, and create and maintain a sufficient reserve to meet all probable replacements, extensions and improvements. The proposed Salina rate should provide sufficient revenue for the fol1owingt (1) Operation and maintenance of existing facilities; (2) Depreciation; (3) Continuous new construction; (4) Amortization of bonds issued for defense housing facilities; (5) Bond coverage; and (6) Maintaining a reserve fund. These will be discussed in this Section: 2. Operation and Maintenance Expense. The amount of funds required to operate and maintain the water works facilities can best be determined by studying the Water Department expenditures during recent years. From these yearly expenditures we may predict the approximate costs for such expenses for possibly ten years in the future, taking into consideration probable increases in the cost of materials and salaries and the increased physical size of the water works system. The operation aad maintenance expense of the system, annually since 1926, and the predicted annual expense through the next ten years is shown graphically by the curve "A" on Plate III, on the following page. In order to show the relationship between operating expense and total pumpage, we have also plotted curve liB" on the same graph, which shows the total annual pumpage from the pumping station records. There is also a relationship between operating expense and the total physical value of the system. This is shown by Curve "C" on the same graph. -8- {) I '" ~ -, ~ (to m ~ ~ ~ s (.)2 () " 0- ;>:0 ~ b ~~ - c S c ~-c: ~ ~ v o q o a .. .. .. ru I "' "' .. ru (Iht' 1-\ \. -I ~ 1 ~fIi I I... \Il I I v 0) I I ~" ~~,I ') 'I (J t 1 <;) , \S ~ " , I I ~' I PTT I ~t'-, 1-+ i- I I~ I I" -I- , "\I I III r I oiL I irr+,_L ;H , 1 -', ' TriA I I I I I 1\ d- J- 1\ ~_ I I I '--,- I I --+--;. 1- +---+--1- I i I I 1 I I I I I 1 I'; I 1 , , : iit~1 \ ++++, ~J~ T :: ~ 11"'\ IT!

Curves A, B and C show that, in a relative manner, the total operating and maintenance expense changes have lagged behind the total pumpage changes and are not immediately affected by years of abnormally low or high total pumpage. Operating expense and total pump age will both increase, but we expect the operating expense to increase at a greater rate than the total pumpage increase, because of the tremendous increase of the physical size and value of the system, as indic ated by Curve II C" . If, however, we will have been proved too conservative in our prediction of the population increase, it will mean that the City will pump and sell more water than predicted without appreciably increasing the operation and maintenance expense. Should this be the case, the total revenue derived from the sale of water will be somewhat higher than anticipated. 3. Depreciation (Replacements). Private utilities always carry an item of depreciation for the purpose of building up a reserve fund with which to pay for replacements. 1funicipal Utilities have found it advisable, also, to include a specified amount in the rate base to pay for mains, pumps and other facilities which have to be replaced. There 'will continue to be minor replacements in t.he existing water works system. On the average, their cost will be in proportion to the total value of the system. The amount of depreciation to be placed on the existing facilities, which have been paid for, depends somewhat upon the condHion of the system. In the past, it has been the practice at Salina to use about 1% of the estimated value of the fixed assets of the system as the annual depreciation item. That percentage, VIh ich appearing to be somewhat low, has apparently been satisfactory and vall be continued in establishing the new water rates. -9- The valuation of the water works system will increase each year as new facilities are added to the system. The total value of the f:!xed assets of the system, therefore, will be about $2,085,000.00 in 1962. (See Plate III on the preceding page). The amounts applied to depreciation each year for the next ten years are shown in the table at the end of this section. 4. Expenditures for Annual New Construction. There will continuo to be a certain amount of distribution system extensions and of reinforcing ma~~s and facilities to be constructed each year. The report on water pressures, submitted in 1950, explains the necessity for larger transmission and distribution mains in portions of the City which have insufficient water pressure at the present time to provide satisfactory domestic service and insure adequate fire protection. The facilities recommended in the report included additional storage and some 16-inch and 12-inch mains. The elevated storage and a part of these mains will now be incorporated in the Defense Housing project, and a part has already been constructed, leavin~ an average of approximately $30,000.00 in new construc- tion annually for reinforcing mains. During the past 11 years, 1941 through 1951, the City has spent an average of $35,238.28 for extensions and reinforcing mains and facilities. The annual expense for the War years, of course, was very low because of the shortage of materials. The annual expense for the period since the 1mr was very high, because of the "catching-upll that needed to be done. Due to the increased cost of materials since the war, it would appear that the cost for ~ew extensions in future years will be somewhat higher than in the past. Therefore, we b91ieve that about $20,000.00 should be provided each year for the construction of new service mains to new develop- ments, and about ~30,0'J0.OO for reinforcing ma.1ns and larger arteries, making an annual total of $50,000.00 for continuous new construction. -10- ~. Defense Housing Project. The immedi.:lte problem confronting the City is the need for feeder and distribllt.:i.~ mains and facilities for the Defense Housing project west of Highway 81 Bypass. This project, in itself, will require the expenditure of approximately $258,300.00 for distribution and feeder mains, hydrants and valves. This expenditure will require the issu- ance of revenue bonds since the present water department funds are inadequate. In order to be able to supply adequate amounts of water to the project area without upsetting the balance of the remainder of the system, it will be necessary to include with the Defense Housing project approximately $91,845.00 worth of l6-inch and l2-inch feeder mains as recommended in the 1950 report; the 500,OOO-gallon elevated tank in the south or southwest portion of the City, costing about $98,000.00; two new water supply wells costing about $22,000.00; approximately 1000 water meters, costing $26,000.00; and a new high service pump costing $15,000.00. The totai expenditures outlined above will amount to $511,145.00. Part of the feeder mains, distribution mains and meters will be required this year. The remainder, and the elevated tank, wells and pump will be required before the end of 1953. It is estimated that funds should be available to pay for $300,000.00 of the work in 1952, and the remaining $211,145.00 in 1953. 6. Bond Coverage. In order to insure against insufficient funds being available to meet the City's Revenue Bond payments during a particularly unusual year in which the water revenues may be low or the operating expenses high, or both, it would be advisable to set up a reserve connnonly known as "Bond Coverage". The amount of this fund need not be large and it is esti- mated that an amount equal to 5 percent of the outstanding bonds will be adequate.

Summary. The foregoing text has pointed out the following pertinent information regarding Salina's water supply facilities: a. Expenditures have exceeded revenues dudng the past 5 years, thereby depleting the reserve funds. b. The defense housing project will require the expenditure of approxi- mately 1/2 million dollars during the next year and one half. c. Construction of scheduled reinforcing mains and distribution mains in new areas will require the expenditure of $50,000.00 annually. d. The population of the City will increase to at least 32,000, and the use of water per capita will increase to approximately 195 gallons per day, by 1962. e. The present water rate strncture is well bala.l1ced, but a flat percentage increase will be required to retire revenue bonds and meet current obligations of the Water Department. f.
